Patented May 6, 193% unirsn stares PATENT OFFICE ROBERT LESLIE BELLHOUSE, OF MANCHESTER, ENGLAND, ASSIGNOR TO THE FINE COT'I'QN SPINNERS & DOUBLERS ASSOCIATION LIMITED, OF LANCASTER, ENGLAND SLUBBING, ROVING, AND LIKE FRAME FOR SPINNING- OR TWISTING COTTON AND OTHER FIBERS Application filed October 15, 1928, Serial No. 312,658, and in Great Britain October 31, 1927.

This invention relates to improvements in slubbing, roving or the like frames for spinning or twisting cotton or other fibers.

The usual double legged fiyer of the usual construction used in such frames and having a hollow leg through which the roving passes to the presser finger, has the disadvantage that fluff and fiber collects in the interior of the hollow leg which is the collecting place for 1 many unseen faults and moreover the legs and the bridge piece connecting the legs together serve as edges for the collection of fluff and fiber and act as paddles for setting up air current causing fibers to be detached from the roving, resulting in waste and faults and filling the atmosphere with fibers, dust and other impurities.

The object of the present invention is to overcome these disadvantages and it consists in replacing the usual two legged flyer by a single solid flyer leg, the rove passing down to the presser finger on the outer surface of the solid leg and the top of the flyer, which carries the single leg being made symmetrical in the form of a circular disc or cover which has no edges or projections to collect fluff or fibers and act as paddles to disturb the air.

The single solid leg may be attached on the underside or on the edge of the flat disc.

The invention will be described with reference to the accompanying drawings Fig. 1 is a vertical section of one form of the invention in which a single fiyer leg is carried by a double casing extending over top of the flyer leg.

Fig. 2 is a section on line 22 Fig. 1.

Fig. 3 is a section on line 33 Fig. 1.

Fig. 4 is a vertical section of a modification.

Fig. 5 is a plan of same.

In the form of the invention shown in Figs. 13 a double casing A extends over the top of the single fiyer leg D and the lower casing A consists of a round disc on the underside of which is mounted a guide D for the flyer leg D. A counterweight w is carried on the upper side of the disc A being placed diametrically opposite the guide D for the flyer leg D. The outer or upper casing A is in the form of a cap which may be flat as shown in Fig. 1, and encloses the top of the flyer leg D, and the counterweight 10 The whole is mounted on a central boss at which forms a socket which fits on the top of the spindle.

The upper part of the boss a is provided with suitable passage through which the roving is threaded. This passage may be of any convenient or suitable shape such as an inclined passage, a vertical passage a connected to a transverse passage a as shown in Fig. 1, or a curved passage. This passage a, a terminates above the top of the cover A as shown.

The roving is threaded through the pass age and is then led across the upper surface of the cap A direct to the fiyer leg guide (Z through a suitable channel or slot (Z in the cap A It is then led down the fiyer leg or its guide, either parallel to, and on the leading face of same, or in coils round same to the guide eye 0 in the flattened end of the presser finger C.

The presser finger C is aiiixed to the bottom of the leg D and is caused to fly inwards by cranking the flyer leg D outwards below its lower bearing. That portion of the flyer leg D which is then outside the axial centre of its bearings, acts as a counterweight which flies outwards due to centrifugal force, and consequently causes the presser finger C to fly inwards.

In the form of the invention shown in Figs. 4 and 5 the fiyer leg D is carried by a bearing D extending downwards from the side of the circular disc A which fits over a socket a mounted on the top of the spindle. The leg is cranked as in Figs. 1, 2 and 3 to cause the presser finger O to fly inwards. The leg D is balanced by the counterweight 'w In the arrangements described above the roving is visible throughout its entire length, whereas it is hidden in the hollow leg of an ordinary flyer which is a collecting place for countless unseen faults.

No time is lost in cleaning as the only projection on which fibers etc. could collect (viz :fiyer leg or its guide) are automatically kept clean by the roving which passes over or round them. The surrounding air is not disturbed to the same extent as is the case with an ordinary two-legged flyer which virtually acts as a paddle and causes fibers to become detached from the roving and blown about, resulting in waste and more faults, and filling the atmosphere with fibers, dust and other impurities which are as injurious to the proper working of the cotton as they are to the health of the workpeople.

WVhat I claim as my invention and desire to protect by Letters Patent is 1. In a slubbing, roving or like frame the combination with a bobbin carrying spindle of a boss mounted thereon, a circular cover carried by the boss, a single cranked solid leg depending from the edge of the cover, a passage through the boss to direct the roving over the top of the cover to the solid leg, a fixed counterweight carried on the cover to balance the solid leg and a presser finger at the bottom of the solid leg to direct the roving on to the bobbin. 7

2. In a slubbing, roving or like frame the combination with a bobbin carrying spindle of a boss mounted thereon, a circular disc carried by the boss, a second disc arran ed above the first disc, a single cranked soiid leg depending from the edge of the first disc, passages through the boss to direct the roving over the top of the second disc to the solid leg, a fixed counterweight mounted between the two discs to balance the solid leg and a presser finger at the bottom of the solid leg to direct the roving on to the bobbin.

In testimony whereof I have hereunto set my hand this 3rd day of October, 1928.

ROBERT LESLIE BELLHOUSE.
